Solve 3^x−5 = 9. Group of answer choices x = −3 x = 2 x = 7 x = 8

Answer:

If an engineer typically makes 50% more than a school teacher, then the engineer's income is 150% of the school teacher's income. Because 100% represents the school teacher's income, and 50% represents the engineer's additional income, the sum is 100%+50% = 150%.

The engineer's income is also 1.5 times as large as the school teacher's income. This can be found by dividing the engineer's income percentage (150%) by the school teacher's income percentage (100%), which gives 150% / 100% = 1.5.

So the engineer's income is 150% of the school teacher's income, and it is 1.5 times as large as the school teacher's income.

Answer: This is evaluataion, To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number.

Step-by-step explanation: In this situation you are going to divide the numerator and denominator by 2. For example 2/8 makes 1/4. 1/4 is equivalent to 2/8 but not fully simplified.

Another way to solve this is to reduce to lowest terms. For example, 5/15 is reduced by dividing the numerator and denominator by 5 to get 1/3.

Divide the numerator and denominator to get a decimal form of the fraction or divide 5+2 by 3+6

Answer:

( - inf, 5) (9, inf )

Step-by-step explanation:

The arrow(s) at the end of the line indicate that the highlighted green line does not stop at a specific number, hence the use of infinity signs (inf). If the arrow is going to the left on a line, then the value would be negative infinity. If it is going to the right, then it would be positive.

As for the space in between the green arrows pointing separate ways, there are two points, one which is positioned at the number 5 and the other at the number 9. Because there are two separate points which are both solid green, the use of parentheses is needed. The final answer is, as mentioned, ( - inf, 5) (9, inf ).

Answer:

No, Jasmine is not correct. The Lowest Common Multiple (LCM) of two numbers is the smallest number that is a multiple of both numbers. Multiplying the two numbers together is not always the correct method to find the LCM.

For example, the LCM of 5 and 8 is 40, but the product of 5 × 8 = 40 is not the LCM.

A more accurate way of finding the LCM is by using the prime factorization of the numbers. By finding the prime factorization of the two numbers, you can take the highest exponent of each prime factor and multiply them together. The result of that multiplication is the LCM of the two numbers.

In this case, the prime factorization of 5 is 5 and 8 is 2^3. The LCM of 5 and 8 is 2^3*5 = 40. So Jasmine's claim that 5 x 8 = 40 and the LCM of 5 and 8 is 40 is not correct.

The percent of the baked foods that are cakes will be 25.33%

It should be noted that a percentage simply has to do with the a value or ratio which can be stated as a fraction of 100. It should be noted that when we want to we calculate a percentage of a number, we simply divide it and then multiply the value that is gotten by 100.

The percentage then refers to a component per hundred. The word percentage simply means per 100 and it is represented by %. In this situation, the bakery produces 280 loaves of bread and 95 cakes daily.

The percent of the baked foods that are cakes will be:

= Number of cakes / Number produced daily × 100

= 95 / (280 + 95) × 100

= 95 / 375 × 100

Serena added 10 grams of sugar to 20 grams of water to make a sugar syrup.

The total amount of sugar syrup made is the sum of the weight of sugar and the weight of water, so:

10 grams (sugar) + 20 grams (water) = 30 grams (sugar syrup)

To find the percentage of sugar in the syrup, we can divide the weight of the sugar by the total weight of the syrup and multiply by 100.

% sugar = (weight of sugar / total weight of syrup) * 100

% sugar = (10 / 30) * 100 = 33.333 %

So the sugar syrup made by Serena contains 33.333% sugar by weight.

It's important to note that the sugar syrup doesn't have only sugar, it also have water, the sugar is just the main ingredient and the percentage of sugar is just the proportion of sugar within the syrup.

Answer: x = 1, -13

Step-by-step explanation:

      We will solve this by completing the square, as asked in the instructions. If we do this correctly, we will end up with a perfect square that will allow us to solve more easily.

Given:

      x² + 12x = 13

Set the equation equal to 0 by subtracting both sides of the equation by 13:

      x² + 12x - 13 = 0

Group the first two terms:

      (x² + 12x) - 13 = 0

Add and subtract [tex]\frac{b}{2} ^2[/tex] to the grouped terms:

      (x² + 12x + 36 - 36) - 13 = 0

Regroup the terms, move the negative out and simplify:

      (x² + 12x + 36) - 49 = 0

Factor the grouped terms (6 is our perfect square here):

      (x + 6)(x + 6) - 49 = 0

Add 49 to both sides of the equation and simplify the factors:

      (x + 6)² = 49

Square root both sides of the equation:

      x + 6 = 7           x + 6 = -7

Subtract 6 from both sides of each equation:

    x = 1           x - 13

The Angle Bisector Theorem states that in a triangle, if a line bisects one angle of a triangle and is also a median to the side opposite of that angle, then the ratio of the length of the median to the length of the side opposite the angle bisected is equal to the ratio of the length of the other two medians.

Therefore, if the angle bisector divides the opposite side into segments 6 cm and 9 cm long, the ratio of the length of the median to the length of the side opposite the angle bisected is 6/9.

Let x be the length of the third side of the triangle.

The Angle Bisector Theorem states: (x/22.5) = (6/9)

Solving for x, we get: x = (22.5 * 6/9) = 15

So the length of the third side of the triangle is 15 cm.

This is the only possible length for the third side of the triangle because the Angle Bisector Theorem only holds if the angle bisector is also a median to the side opposite of that angle.

Answer: D - 124°

Step-by-step explanation: Since y and a are vertical angles, we can determine that angle a is equal to 34°

90° + 34° = 124°

180° - 124° = 56°

Now we know the last angle in the triangle. Since this angle is on the same line as angle b, subtracting it from 180 would give us angle b

180° - 56° = 124°

Answer:990

Step-by-step explanation:10%=0.1

X*0.1=99

99/0.1=990

x=990

The horizontal axis is the real axis and the vertical axis is the imaginary axis. We find the real and complex components in terms of r

and θ

where r

is the length of the vector and θ

is the angle made with the real axis.

From Pythagorean Theorem :

r2=a2+b2

By using the basic trigonometric ratios :

cosθ=ar

and sinθ=br

.

Multiplying each side by r

:

rcosθ=a  and  rsinθ=b

The rectangular form of a complex number is given by

z=a+bi

.

Substitute the values of a

and b

.

z=a+bi    =rcosθ+(rsinθ)i    =r(cosθ+isinθ)

In the case of a complex number, r

represents the absolute value or modulus and the angle θ

is called the argument of the complex number.

This can be summarized as follows:

The polar form of a complex number z=a+bi

is z=r(cosθ+isinθ)

, where r=|z|=a2+b2−−−−−−√

, a=rcosθ  and  b=rsinθ

, and θ=tan−1(ba)

for a>0

and θ=tan−1(ba)+π

or θ=tan−1(ba)+180°

for a<0

.

Example:

Express the complex number in polar form.

5+2i

The polar form of a complex number z=a+bi

is z=r(cosθ+isinθ)

.

So, first find the absolute value of r

.

r=|z|=a2+b2−−−−−−√    =52+22−−−−−−√    =25+4−−−−−√    =29−−√     ≈5.39

Now find the argument θ

.

Since a>0

, use the formula θ=tan−1(ba)

.

θ=tan−1(25)    ≈0.38

Note that here θ

is measured in radians.

Therefore, the polar form of 5+2i

is about 5.39(cos(0.38)+isin(0.38))

.

The alternate angle theorem states that when two parallel lines are cut by a transversal, then the resulting alternate interior angles or alternate exterior angles are congruent.

State Alternate angle theorem?

The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs. These angles are called alternate interior angles.

When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.

Angles that are on opposite sides of the transversal are called alternate angles. All angles that are either exterior angles, interior angles, alternate angles or corresponding angles are all congruent.

In the above-given figure, you can see, two parallel lines intersected by a transversal AB.

So according to the alternate angle theorem,

m∠3 = m∠6

Now moving on to the students' explanations, both logics are correct.
